10. Nebius Group NV (NASDAQ:NBIS)

Nebius Group dropped its share prices by 5.4 percent to close at $128.15 apiece as investors unloaded positions while in a wait-and-see mode for more catalysts to boost buying appetite.

Investor enthusiasm appeared to have already cooled down after pricing in news of an $18 billion cloud computing deal with technology giant Microsoft Corp.

Under the deal, Nebius Group NV (NASDAQ:NBIS) would deliver the capacity from its new data center in Vineland, New Jersey, with capital expenditures targeted to come from a combination of cash flow from the deal and the issuance of debt.

Last month, Nebius Group NV (NASDAQ:NBIS) successfully raised $1.15 billion in fresh funds through the issuance of convertible senior notes and its underwriters’ exercise of their option to purchase over 1.6 million shares for a total of $150 million.

Additionally, it may tap other financing options to enable significantly faster growth than originally planned.

9. Sandisk Corp. (NASDAQ:SNDK)

Sandisk saw its share prices decline by 5.44 percent on Tuesday to finish at $127.29 apiece as investors continued to be in a wait-and-see mode amid renewed trade tensions between the US and China.

Despite being a US-based company, Sandisk Corp. (NASDAQ:SNDK) is particularly at risk in the trade spat between the two countries, having its manufacturing operations located in China.

Additionally, the drop can be attributed to early profit-taking following the previous day’s 15 percent gain, thanks to Goldman Sachs’ whopping price target upgrade to $140 from $55 previously.

Goldman Sachs said it maintained its “buy” recommendation for Sandisk Corp. (NASDAQ:SNDK).

In other news, Sandisk Corp. (NASDAQ:SNDK) said it is scheduled to announce the results of its first quarter earnings performance for the fiscal year 2026 on November 6, 2025. A conference call will be held at 4:30 PM ET to elaborate on the results.
